Link to Ghost-Post only working with www

So I've set up my own little Ghost-Blog, and I am hosting it on evennode and have a domain at namecheap the problem now is everytime I want to go to a Blog-Post directly i have to include www so for example http://ift.tt/1O9qJW1 and if don't include www for example http://myBlog.com/post it automatically redirects me to my homepage i.e http://myBlog.com. Does somebody know why this is happening?

I guess it's something similar to Ghost blog - links does not work with custom domain but there is no real answer there

Additional info: It works fine if I look at the blog using the evennode domain (i.e http://ift.tt/1O9qJW3)

Thank you for your help!
